Fig. 7. Abnormal L–R molecular marker expression in Xenopus and zebrafish Zic3 morphants. (A) Pitx2 expression in Xenopus Zic3 morphant embryos at stage 30. Embryos were photographed from both left and right sides. Red arrows highlight pitx2 expression. (B) Quantitative results of pitx2 expression in non-injected control (CTRL), control morpholino (CTRL MO) and Zic3 splice site morpholino (SS MO). (C) Southpaw (spaw) expression in zebrafish Zic3 morphant embryos. Red arrows highlight gene expression as left, right, bilateral or absent. (D) Quantitative results of spaw expression in control and Zic3 morphants. |
